Please join us here at Freeport Wild Bird Supply as we welcome back Cameron Cox, this time to celebrate his new book in the Peterson Reference Guide series, SEAWATCHING: EASTERN WATERBIRDS IN FLIGHT.

But this is not just a “regular” book signing. Instead, this is what we hope will be only the first installment of a new “Birds, Books, and Beers” series in partnership with our good neighbors at the Maine Beer Company! Enjoy some of the finest beer around with some of the finest birders in the world!

Cameron will be at our store from 5:30 to 6:15 pm to sign copies of his new, much-anticipated book that will be of great value to birders in Maine – and we know that a few Maine seawatching locales are covered. We’ll have plenty on-hand for you to purchase. We’ll mingle and chat until it’s time to head over to MBC (two buildings away). There we will enjoy fresh beer (it’s our favorite beer in the state!) in the tasting room – from perennial favorites like Peeper, Lunch, and Moe to single-batch pilots – as Cameron will offer a presentation entitled: “Birds In Flight: Beyond Hawkwatching”. The use of flight style and other in-flight traits is well established for identifying distant raptors, but what about for other birds? The slide show will feature photos from the new book and will cover identification techniques highlighted to improve your ability to recognize not just waterbirds, but distant birds of all types in flight.

No doubt another round of beer will follow. Cameron will have a pen in hand to sign his book and we will have more books for sale at the brewery for those that arrive later. Light snacks and non-alcoholic beverages are also available for purchase.

We think you will find this new casual format for our regular author appearances to be a lot of fun, so we hope you will join us!

Yesterday, I had the pleasure of leading our annual “York County Rarity Roundup” Field Trip for York County Audubon today. With no rarities to “round up,” we set out to find our own, birding from Kittery through Wells. We followed a very similar route to what Jeannette and I always do on our monthly south-coastal run. The difference today was that with a group, and with so many birds at FortFoster, we never made it out of Kittery by lunchtime. Too bad that meant we just HAD to have lunch at Loco Coco’s Taco (mmm, chili relleno burrito…)!

It was a very birdy day overall, even in the windy afternoon. A preliminary total of 63 species of birds included 9 species of sparrows, 5 species of shorebirds, and 4 species of warblers. Excellent-for-the-season bird diversity was augmented by 5 species of butterflies, 3 species of mammals, 2+ species of dragonfly, 1 reptile (Garter Snake), and 1 amphibian (Spring Peeper).

The bird of the day by far was “Audubon’s” Yellow-rumped Warbler that I found at FortFoster. This western subspecies of Yellow-rump (it once was, and I believe will likely once again be considered a full species) has only occurred – or should I say, been detected – in Maine a few times. I can only think of one recent record, an adult that nearly-overwintered at Dyer Point in Cape Elizabeth a few years ago.

If anyone wants to look for it, the bird was flycatching and occasionally eating Red Cedar berries along the west edge of the park. Follow the entrance road into the park, until the large gravel parking lot opens up on the left. The bird was loyal to the right (west) edge here, especially around the big cedars in the mowed lawn.

Noah Gibb and I photographed the bird extensively, and I was also able to borrow a phone to get a voice recording. All aspects of the bird – from plumage to voice – fit perfectly with a pure “Audubon’s” Warbler.

I first glimpsed the bird sallying for insects in and out of shadows. The overall extremely cool gray plumage tone – top to bottom – brought to mind a first fall female Pine Warbler. But something wasn’t right. The bird began to call, and that was definitely not the call of a Pine Warbler…but what was it? We saw the bird briefly a few times, the pieces began to come together, and then as it flew to another tree the bright yellow rump became evident. “Audubon’s Warbler!!!!” I exclaimed.

We studied the bird extensively for at least a half hour, occasionally in perfect light for prolonged periods. I scribbled notes, and encouraged others to do the same before we discussed the bird any further. Plenty of “Myrtle” Warblers (the Eastern subspecies of Yellow-rumped) were nearby for convenient comparison.

– Obvious “Yellow-rumped” Warbler with bright yellow rump, overall size and shape, bill size and shape, etc.
– Exceptionally cool gray overall plumage tone, not suggesting the brownish tones of even the palest Myrtles.
– Very diffuse streaking below.
– Very restricted and pale yellow “blobs” on sides of chest.
– Very subtle and restricted yellow on throat, not visible in all light conditions, but quite obvious in good sunlight.
– Lacked the extension of pale on the throat that “points” up around the back of the auriculars as on Myrtle. Therefore, throat patch appeared rounded, or encircled by the cool gray of head.
– Auriculars only marginally darker than rest of head, often looking concolorous.
– Call note very different from surrounding Myrtles, much sharper and not as “blunt.”
– Exceptionally dull plumage highly suggestive of a first fall female, but the lack of a definite molt limit within the greater coverts prevents us from clinching the age. (reference: The Warbler Guide, Stephenson and Whittle, 2013)

Good bird! And yes, Rarity Season is most definitely in full swing! Good thing it appears that, after a prolonged drought, I have finally refound my rarity-finding mojo. Phew.

Now, about that Saltmarsh Sparrow – which I admittedly called an “Interior” Nelson’s Sparrow in the field… Expecting to see an “Interior” Nelson’s Sparrow based on the timing, micro-habitat, and behavior, I reached for my camera before I fully studied the bird. After firing off some photos, and making sure everyone got on the bird, it took off and we never saw it again. Although I mentioned that the malar looked “quite dark,” I didn’t second-guess the call until I looked at photos on the computer this afternoon. Yeah, it’s a Saltie. The malar is not only dark and distinct, but it frames a clear white throat. The breast streaking is dark and extensive, the bill has a fleshy-pink cast, and it is simply too long-billed for an “Interior” (subspecies alterus or nelsoni; I don’t believe they are identifiable in the field). As a final clincher, note the fine streaks towards the rear half of the supercilium. Behavior and timing wise: odd for a Saltmarsh. Plumage: essentially textbook for a Saltmarsh. Therefore, “After further review, the call (in) the field is overturned.”

I actually expected more juncos and especially White-throated Sparrows (at least in the parking lot, they almost never cross the water here), but the American Robin count was actually my third highest here. The redstart, one of the first birds of the morning, was definitely unexpected – it has been several weeks since I have seen one.

So was this my last good flight at Sandy Point? I sure hope not, but the calendar is getting late. There’s no doubt there is still a big push of juncos at least. But we’ll see if the weather conditions cooperate.

Meanwhile, as SandyPoint winds down, “Rarity Season” starts to pick up. There’s our Bell’s Vireo in Harpswell, an Ash-throated Flycatcher on Monhegan, a Pink-footed Goose that was up in The County, and the usual smattering of fun fall stuff like a White-eyed Vireo or two, a couple of juvenile Red-headed Woodpeckers, and a sprinkling of “late” birds in no doubt partially due to the mild season. I believe there are symptoms of Rarity Fever welling up inside me!

In other words: MEGA! And needless to say – especially since I missed the two from last year, despite my best efforts – this was a thrilling find, capping a very productive morning of birding Bailey Island that included a Yellow-breasted Chat (my first of the year) at Land’s End, and a total of 5 species of warblers on Bailey Island this am: Hundreds of Yellow-rumps, and one each of Black-throated Blue, Black-and-white, Common Yellowthroat, and Blackpoll. Song Sparrows, Dark-eyed Juncos, White-throated Sparrows, and other seasonal migrants made for a very birdy visit.

In what turned out to be our last stop of the morning, Jeannette and I walked Abner Point Road. Upon reaching a promising thicket (see directions below), I began to pish. Yellow-rumped Warblers and a Winter Wren responded immediately, and as Jeannette attempted to photograph the wren, I sorted through the yellow-rumps, hoping to find one with a yellow throat. A handful of minutes later (about 10:35am), we heard a harsh, scolding chatter emanating from the dense vegetation. “Vireo?” Jeannette asked quizzically as we both looked at each other, unsure of the sound – it sounded like nothing we are used to hearing. I wondered out loud about a Carolina Wren making some odd sound (they’re good at that, and there was one in that particular thicket), and the nasal quality led me to consider a funky Red-breasted Nuthatch. We looked hard but could not turn up anything that fit the sound.

About 5 minutes later, a small vireo pops out of the brush in front of me. At first I called “White-eyed Vireo” due to the bright yellow flanks and overall shape, but then I got a clear look at the head. “BELL’S VIREO!” I exclaimed, as Jeannette, a few yards away still working on photographing the wren rushed over.

As is often the case for Bell’s Vireos, it quickly ducked back into the cover. I continued to pish, and the bird popped back up. I had a second brief, but unobstructed view of the whole bird. Jeannette went for the camera, and prepared to fire away, only to see the bird dive back into the shadows once again. One last brief glimpse of the bird was all we would have for the next hour.

We searched hard, but could not relocate it. A Blue-headed Vireo was more cooperative, and permitted us some comparison. We listened to a recording of the call of a Bell’s, and there was no question in either of our minds’ that is what we had heard earlier.

We thought we heard that call in the distance of the thicket one more time, and perhaps even a snippet of a song, but background noise and an increasing southerly wind made us unsure of that. And that wind was clearly not making this skulker any more likely to show itself. At 11:50, we heard the distinctive call once again, but from thick shrubs behind a house across the street. We hustled over, but unfortunately only managed to pish in a cat (one of at least five in this immediate area; it was worse than Monhegan!), which was likely the object of the vireo’s recent ire. We worked the area as best as we could, and eventually saw the homeowner in her yard and received permission to wander around. No luck. We had also received permission earlier from the homeowner adjacent to the first thicket to check her yard, so we did another circuit, but we came up empty, and it was getting breezier and cloudier. Lunchtime was calling us, too.

While I left with almost three pages of field notes, it was rather frustrating to not get a photo, especially since Jeannette was so close to snapping it! However, as a firm believer in the value of written field notes for documentation of rare birds, I scrawled away in my notebook. Here are the particulars, after seeing the entire bird well a couple of times, with notes entered in rough order of observation, not in order of relative importance (edited only for context, not content):

– Overall relatively dully-marked, small vireo. Body shape and size, and brief glimpse of the body color first suggestive of White-eyed Vireo, the expected rarity here.

– Fairly bright and extensive yellow on sides, from chest through undertail (suggestive of the Eastern subspecies?)

– One fairly bright whitish wingbar, on the tips of the greater coverts. An indistinct second wing bar, presumably on the edges of the lesser coverts, was discernable, but did not stick out. Not the bold, bright white double-wing bars like Blue-headed Vireo.

– Head grayish, perhaps with a hint of an olive cast.

– White or off-white throat contrasting with gray head and face and yellow on the rest of the underparts.

– Very dull face pattern consisting of a partial eye-ring (or perhaps best described as two eye-crescents) and indistinct supercilium restricted to in front of the eye. Maybe a small hint of a supercilium a very short distance behind the eye, but I am unsure of this. A darker line, or narrow smudge, through the eye gave a subtle hint of a face pattern reminiscent of a darker Warbling Vireo or very pale Philadelphia Vireo.

– Perhaps due to the angle, I though the bill looked relatively long compared to the size of the head, but it was clearly rather narrow for a vireo, and was diminutive compared to the Blue-headed Vireo observed a short time later.

– Relatively long-tailed (NOTE: although in comparing photos later, I wondered if it was actually suggestive of the shorter-tailed Eastern subspecies).

– The first view was of a “sleeker” or slimmer vireo, not the chunky, broad-chested shape of Blue-headed.

– Very active, and did not come out into the open for very long (NOTE: tail movement not seen, or not noticed, which could have been a good key for subspecies), always disappearing into low, dense brush.

In comparison to other species:
– Wingbars and bright yellow underparts distinguish it from Warbling Vireo.

– Lack of yellow in the throat and pale face pattern, along with wing bars and fairly long tail and slim shape help distinguish it from Philadelphia Vireo.

– Incomplete eye ring and lack of broad and bright yellow spectacles separate it from White-eyed Vireo. Wings paler and less contrasty, and no contrasting pale gray nape as on WEVI.

Directions to the bird (although I have not heard any reports, positive, or negative, about the bird as of 4:00pm today):
To reach the thicket we first found it in, take Rte 24 from Cook’s Corner in Brunswick south through Orr’s Island and onto Bailey’s. Make a right onto Abner Point Road at the Johnson Field Preserve. Park on your left in the gravel parking lot for the beach. Walk down Abner Point Road a couple hundred yards, around the bend. On the right, you’ll see a small parking lot with little white signs with people’s names on them. The bird was in the thicket behind these signs, along with a Blue-headed Vireo and a mess of Yellow-rumps.

When the Iowa Ornithologists’ Union invited me out to be the Keynote Speaker for their 2013 Fall Meeting, I jumped at the opportunity to get some birding in in a part of the country that I have not spent very much time exploring. Add to that a program and book signing at Milwaukee’s Urban Ecology Center, and I had a solid excuse to work on some under-served state lists…and visit some good friends. Each day, I posted a short synopsis of my travels and birding on my book’s Facebook page. Here, I’ve simply edited those and added some photos for your viewing pleasure.

10/10: Travel to Des Moines, Iowa. Departing Portland at 6:14am.

10/11: Ankeny, Iowa.
On my way to the Iowa Ornithologists’ Union‘s Fall Meeting, I spent the first day and a half of my trip birding the Des Moines-Ankeny area with my friend Danny Akers, the 2009 Bradbury Mountain Spring Hawkwatch Official Counter.

I had hoped for Smith’s Longspurs to fill in a gap on the ol’ life list, but unfortunately, we came up empty, despite a few miles of walking up and down short-cut fields at a couple of locations. While a stiff southerly wind has not helped, they just don’t seem to be “in” yet. Unseasonably warm temperatures – a high of 78 yesterday for example – has likely put quite a few fall arrivals behind schedule.

A nice consolation prize for me, however, was a fair number of LeConte’s Sparrows – a bird I really like, but don’t get to see too often. Other birds that were a treat for me include Franklin’s Gull, Sedge Wren, Red-headed Woodpecker, and American White Pelican. Our best bird, however, was probably the Pileated Woodpecker at Waterworks Park in Des Moines – a long overdue Polk County bird for Danny.

But as always, I just flat out enjoy birding new places. And since I’ve only barely birded Iowa once before, my state list is growing by leaps and bounds. I was not too happy that I was unable to bird the famous Saylorville Reservoir, however, thanks to the government shutdown. John Boehner: you owe me some state birds!

We then headed east towards Clinton, where Danny and I would be leading a field the next morning. I very much looked forward to seeing what might be moving behind this approaching cold front. While it might not clear in time for a flight tonight, Sunday morning could be a lot of fun.A phone-binned juvenile LeConte’s Sparrow.

10/12: Clinton, Iowa – Iowa Ornithologists’ Union Fall Meeting.
Danny and I led a field trip this morning to Princeton Marsh here in Clinton, IA. We had a great turnout – I was honored! – of birders. I just wish there were more birds than mosquitoes!

Few migrants were around in the morning; there was no morning re-determined migration today. The approaching cold front took its sweet time in getting here, and had not pushed through easternmost Iowa by dawn. It was interesting to see the huge flight on the Des Moines radar overnight, just west of the front, compared to the Davenport radar, just east of the front (where we were).

So the woods were quiet, but we had ample numbers of things like Yellow-rumped Warblers, both kinglets, and lots of Red-winged Blackbirds commuting overhead. A heard-only Pileated Woodpecker and a good look at a Winter Wren were local highlights. Oh, and I got a life frog: Cricket Frog! And lots of Leopard Frogs were around; it was not a good sign that I was ranting about bush honeysuckle and playing with frogs within the first 30 minutes of the walk.

A scrubby, weedy wetland area near the southern edge of the property was much birdier, however, highlighted by a teed-up LeConte’s Sparrow, 7 Wilson’s Snipe, and a Sora. A small group of 5 Eurasian Tree Sparrows were a little unexpected.

The front had now pushed through, dropping just a few sprinkles, but also blowing away the skeeters. That was nice. Danny and I decided to try a little river migration watching, so we headed over to a small riverfront park in Princeton that intrigued us during a quick visit yesterday.

Now we were in business! A trickle of raptors began to move overhead, as soon as the clouds cleared. A handful of Sharp-shinned Hawks, a Merlin, a few Red-tails, etc. A group of about 30 Franklin’s Gulls sitting on the sandbar took flight, soaring high and perhaps southwards. As we were about to depart, a line of 32 American White Pelicans came cruising down the river. Yay, migration in action!

In the afternoon, I presented my Russian Far East: In Search of the Spoon-billed Sandpiper program. Yeah, I apologize I went a little long there. Oops. But it was such a great experience to share, and really, is there ever such thing as too many Tufted Puffin pictures?Home base for the Meeting.

Early morning in Princeton Marsh.

10/13: Clinton, Iowa.
What a difference a day makes! A very strong flight took place overnight Saturday into Sunday, and a lot of birds arrived for Sunday morning.

Not only was I very happy to see a lot of birds on our field trip to Princeton Marsh, but I was happy to see that my predictions came to fruition. Following my evening program “A Sandy Point Case Study,” in which I concluded with a little local radar analysis, I predicted it was going to be a good morning (it’s always a risk sticking one’s neck out like that!). And it certainly was at Princeton Marsh at least!

Large numbers of Yellow-rumped Warblers were reorienting overhead at dawn, and new arrivals included Palm Warblers and Fox Sparrow. Some waterfowl also arrived with Blue-winged and Green-winged Teals, and Gadwall becoming new entries in my state list. 2 Nelson’s Sparrows joined two LeConte’s Sparrows; both species were seen very well by all, and Nelson’s is fairly rare around here.

Very local in Iowa, a conspicuous Pileated Woodpecker was enjoyed (a lifer for some, actually), as was a spiffy adult Red-shouldered Hawk. But the bird-of-the-day was a very truant adult White-faced Ibis that was foraging in a shallow wetland.

A great morning of birding concluded a most enjoyable and productive weekend for me. I thank the Iowa Ornithologists’ Union for having me out, and I hope to see you again soon!Princeton Marsh.

10/14: Clinton, Iowa:
Danny and I headed north this morning. Our first stop was the Goose Lake WMA.

After another good flight on the radar overnight, we found a lot of birds here. American Robins, White-throated and Swamp Sparrows, Red-winged Blackbirds, Cedar Waxwings, and Song Sparrows were all abundant, trumped only by the cloud of 500+ Tree Swallows.

A flock of Rusty Blackbirds were in the marsh, along with a single Ring-necked Duck – the last two new species for my Iowa list of the trip. The highlight for me, however, was the 60+ Wilson’s Snipe that joined ~25 Killdeer on a mudflat in the marsh; I’m not used to seeing so many snipe together.

We then drove to Madison, Wisconsin, picked up David La Puma and new friend Jessica Gorzo, and – in what, in hindsight was not a great idea – raced north to chase a long-staying White-tailed Kite. Not that an occasional chase with friends is a bad idea, but the fact that we were essentially racing the sun made us reconsider this.

Arriving in the area with about 30 minutes to sunset didn’t provide much hope, but an ultra-distant male Northern Harrier hovering over a field did – at least for a little while. Flocks of Sandhill Cranes were heading to roost, as was a massive cloud of Canada Geese. No small – in my mind – consolation prize, however, was the flock of about 30 Greater Prairie-Chickens that I spotted as they flew just over the tops of a field, before disappearing into the grass. Although known to be here – and intensively managed for them – they are not often seen, especially at this season, so that was a real treat for me. Having seen Greater Prairie-Chicken many fewer times than White-tailed Kite, I left satisfied. Mostly.Goose Lake WMA.

“I think it’s too late” – All of us.

10/15: Madison, Wisconsin.
Danny said goodbye and took off in pursuit of the White-tailed Kite once again (unfortunately, despite many people looking it was not seen, and has never been seen again. Apparently, we missed it for good by exactly one hour). David and I wished him luck, but we thought our time would be better spent birding locally in Madison before heading over to Milwaukee.

The Pheasant Branch Conservancy was our destination – after a ridiculously late start for all (our respective travels had clearly caught up with all of us!). While the radar did not suggest that this was a morning that could not be missed, we probably – it’s October afterall – should have motivated sooner, but sometimes the body makes such decisions for you.

However, even in the middle of the morning, this Middleton preserve was decidedly birdy! It was full of sparrows, and my paltry state list grew by leaps and bounds. Fox Sparrows had arrived, White-crowned Sparrows were in good numbers, and plenty of White-throated and Song Sparrows were to be found, along with a goodly number of Lincoln’s Sparrows – one of my favorites!

Before we knew it, however, it was time to head to the Urban Ecology Center for my evening program. At a pre-presentation dinner, it was great to meet some new friends, and get re-acquainted with some of the people who joined me (OK, technically, I joined them) aboard the UEC’s private charter aboard the Schooner Lewis R. French out of Camden, ME last summer. They were stuck with me for 5 days yet came back to hear me talk even more, so I guess that is a good sign!

I wanted to thank Tim Vargo of the Urban Ecology Center for inviting me over, and I thank everyone who came out last night. I hope you all enjoyed the show!

10/16: Madison, Wisconsin.
Following my Sandy Point Case Study presentation at the IOU Meeting over the weekend, I looked at the local radar with the group and suggested it would be a very good morning in the field. And, in most places, it definitely was. After my Urban Ecology Center program last night, we looked at the radar and saw virtually nothing that suggested bird migration.

David chastised me a little bit for even hinting that “no migration on the radar” means “don’t go birding in the morning.” “It’s migration – go birding every morning!” (My point in the progrAm was simply that I would not have gone to Sandy Point that next morning). And he’s absolutely right. There are plenty of birds around in mid-October even when they have not moved in the night before.

While there might not be a Morning Flight of note without many “new” birds, there are plenty of birds in the field – literally. It’s sparrow season, and just to prove the point, local Madison birding once again proved why you go birding every day in migration! First, we walked through the woods from David’s neighborhood to the 1918 Marsh. Not much happening. A walk around and through the marsh, out to Picnic Point. A little dissapointed by the low numbers of sparrows, we instead enjoyed a nice little sampling of newly-returned migrant waterfowl (Northern Pintail, Bufflehead, Gadwall, American Wigeons, and Redhead), and lots of American Coots. Coots always amuse me. And drake Wood Ducks are always worth and extended view.

Readers of my blog and the store’s Facebook Page know I am a big fan of birding community gardens in the fall, so you could image my glee when we exited the Biocore Prairie (which itself had a goodly number of sparrows) and I stepped into the acres of the Eagle Heights Community Garden. This is where all of the sparrows were! 400+ House Sparrows, 150+ American Goldfinches, 100+ White-throated Sparrows, 75+ Song Sparrows, 50+ White-crowned Sparrows including one of the western subspecies Gambelli. A couple of dozen Lincoln’s Sparrows and Dark-eyed Juncos. A smattering of Field Sparrows, Yellow-rumped Warblers, and Chipping Sparrows. A handful of Palm and Orange-crowned Warblers, 1-2 Fox Sparrows, and my 100th Wisconsin Bird: 2 Brown-headed Cowbirds. Times flies (as in almost 3hrs here!) when you are having fun!University of Wisconsin from 1918 Marsh.

10/17: Madison, Wisconsin.
This was my last day of birding of my little Midwest trip. After David and I hit the Eagle Heights Community Garden in Madison (more juncos and Chipping Sparrows, 1 Nashville Warbler, multiple Orange-crowned Warblers, a late Ruby-throated Hummingbird, a continuing “Gambell’s” White-crowned Sparrows, etc), I hit the road for Minneapolis.

Visiting a non-birding friend – yeah, sometimes I tolerate hanging out with people that don’t like birding – my birding was limited to a walk around LoringPark and the art museum’s SculptureGarden. White-throated Sparrows were quite common, with a fair number of Dark-eyed Juncos, Swamp Sparrows, and a couple of Lincoln’s Sparrows. There was actually a reasonable diverse selection of migrants in this small, very manicured city park. And I do love city park birding!

10/18: Minneapolis, Minnesota.
As much as I love to travel, I love to come home even more! It’s good to be back, but I thoroughly enjoyed my time birding, visiting, and chatting about “How to Be a Better Birder” in Iowa and Wisconsin. Thanks again to the Iowa Ornithologists’ Union, Tim Vargo at the UrbanEcologyCenter, Danny Akers, and David La Puma for making this tour happen.

After three nights with little to no migration, birds took to the skies en masse come nightfall last night. It was a big flight. For examples, here are the 10pm, 1am, and 4am reflectivity and corresponding velocity images:

That’s a heckuva flight! But as October goes on, more and more of the migrants are sparrows. Most sparrows (juncos and Chipping Sparrows are the exceptions) do not partake – or barely so – in the morning re-determined migration (“morning flight”), at least at Sandy Point, so I have been disappointed with the tally come dawn at Sandy Point on more than one occasion in mid-October. While this morning’s flight was still good, it was not as busy as I would have expected based on the density of those radar returns. But there were a lot more sparrows around in the bushes at Sandy Point and elsewhere this morning; I wonder what percentage of last night’s flight were White-throated Sparrows?

At the bridge at Sandy Point, the morning’s flight started out quite slow. By 7:30, I had even considered packing it in and going to look for sparrows. But then things picked up a little bit, and a steady trickle of birds slowly added up to a respectable tally. Both kinglets spent a lot of time swirling around the point this morning (as usual, I was conservative in my count of how many were actually crossing, as many would turn around, come back, and try again), and the sparrow tally was probably a lot higher. However, by the time I left the bridge, most White-throats had already dispersed into the woods. Song Sparrows – which I do not attempt to tally due the number of breeding birds in the powerline cut – were definitely more abundant than they have been as well.

Afterwards, I did a circuit of the local “goose fields.” As with everywhere to our south, the resident, non-migratory population of Canada Geese is burgeoning in southern Maine. This resident population begins to coalesce in the fields of Yarmouth, Cumberland, and Falmouth in early August, and by the middle to end of September, the flock includes a sizeable percentage of the local breeders. The percentage of local breeders that are in the fields on any given day increases with the onset of early Canada Goose hunting season in early September.

This year, the number of geese among all fields has varied between 200-300 total birds since early September. This number of pre-migrant birds has grown steadily over the past five years in particular. This week, the first real influx of geese arrived, presumably from some points north. It is the flock of resident geese that know the safe fields (no hunting, less Bald Eagle activity) and travel corridors to and from the bay where they roost that attract the migrants, including those occasional rarities.

My high count this week of 445 Canada Geese today was my highest tally since the spring. A couple of Eastern Meadowlarks and up to 8 Killdeer were also present at Thornhurst Farm this week, and Eastern Bluebirds have been rather widespread. A Pied-billed Grebe was once again in the pond on Woodville Road in Falmouth, as is often the case at this time of year.

The goose numbers and the chance for finding rarities should only increase (well, with various ebbs and flows) from now through the first heavy snow. In fact, I often find my first “good” goose in the second week of October. It’s also primetime for sparrows. And this is why I hate leaving the state in October, but once again, I am off!

Early tomorrow morning I depart for Iowa, where I will be speaking at the Iowa Ornithologist Union’s Fall Meeting. I’ll be giving the keynote presentation on “How to Be a Better Birder” using my SandyPoint case study program and I will also be showing my Russian Far East travelogue. Finally, I will be joining the 2009 Bradbury Mountain Hawkcounter, Danny Akers, in leading a field trip.

After my weekend in the Hawkeye State, I head to Wisconsin to visit the Urban Ecology Center in Wisconsin. In between and thereafter, I’ll be spending a couple of days birding and visiting with friends. I’ll post the occasional update about migration in the Midwest, my birding, and other musings on my book’s Facebook page should you be interested in following my travels.

Now I am just left to wonder what state bird I will miss here in Maine while I am away (there’s always one!)

An otherwise slow morning flight (more on that shortly) was interrupted by an odd call emanating from upriver of the bridge. “Hmm, sounds like a Black Skimmer, I thought.” Uh, wait…but alas, there it was! It alighted on what was left of a small sandbar with a couple of gulls, and as that sandbar became inundated, it took to the wing again and began to forage. I lost sight of it as it moved up the bay, but a little pocket of Palm Warblers moving through distracted me.

Looking at the radar last night, the flight seemed strong, but the Morning Flight was decidedly slow. Here are the 1am radar and velocity images for example:

A couple of things are noticeable. For one there’s the fairly narrow diameter of the flight reflection which would suggest a low flight (the radar beams well out from the tower are above the height of birds; the “angle of elevation). This definitely happens when birds, such as sparrows – and they’re definitely on the move right now – which tend to fly relatively low dominate the flight. So perhaps a lot of the flight last night was of the sparrow variety.

However, the velocity image suggests the north to south motion was rather slow. Perhaps it was just because it was so calm and slower-flying migrants were in the air and therefore were making less progress (ground speed). Or maybe there’s a lot of dust and bugs up there; it has been warm and dry after all.

Regardless of the explanation, or lack thereof, the flight was slow. But did I mention I had a Black Skimmer?

Afterwards, I decided to check on my “lots of sparrows moving last night” hypothesis, so I visited Old Town House Park. There were an ample amount of sparrows (30+ Song, 20+ Swamp, a small number of White-throated, 2 Lincoln’s, 1 Savannah, and 1 White-crowned), but not enough to conclude much about the composition of last night’s flight, or lack there of. But it was pleasantly birdy, with a nice sprinkling of other migrants, including 11 Eastern Bluebirds, 2 Pine Warblers, and the first Purple Finch that I have had in a couple of weeks.

Meanwhile, in the goose fields, things have not yet begun to heat up. While there may be some bona fide migrants around, my tally of 283 Canada Geese today fits right there within the 200-300 that have been present since late August, when the local resident birds began to flock up post-breeding. This will change soon.
